One of the octagonal pulleys O is machine withthe pallet conveyer shown in driven by the ratchet wheel 0, seen at thecross section arranged near the end of the left of Fig. 1, and the pawlo and the confixed bed, just underneath the ejector mechanect-ed parts 00 &c., which connect such nism and adjacent to the line of travel of thepawl to the main driving wheel or shaft Z of 40 molds over such bed, andthe mechanism for the machine. This construction of brick moving thepallets to and from the molds machine is preferably provided with meansto receive the brick or other structures by which the material in themolds is rewhile being ejected therefrom. Fig. 2 shows pressed beforebeing ejected therefrom. The in side elevation the pallet conveyer andits machine shown in the drawings is provided eratin mechanism combin dwith the with a combined repressing and ejecting. seen in elevation inFig. 1, means arranged in juxtaposition to the line brick machine, inend elevation. Fig. 3 shows in plan view of travel of the molds and theend of the a portion of the mechanism for operating stationary bed X bywhich the molded or the pallet conveyer in unison with the operaformedbrlck in one mold is repressed and 50 tion of the brick machine. Fig. 1shows the such repressed brick in another or preceding bar of thescoring device seen in Fig. 1. Fig. mold is ejected at each completemovement 5 shows in plan view a portion of the molds of thereciprocating head of the ejecting seen in Fig. 1. Fig. 6 shows in planview means, which is provided with suitable dethe preferred arrangementof the conveyer vices to simultaneously act on the brick in 55relatively to the brick machine. Fig. two molds at the same time, asexplained shows in side elevation a portion of the below. This mechanismconsists of two carried the .ing mechanism B parts simultaneouslymovable, a and I), respectively, which are fixedly secured to a movablehead B movable upwardly and downwardly in a fixed frame B, byoperatsuitably connected to the main driving parts of the brick machineas seen in Fig. 1. The material in the molds that are in position toregister with the head B and parts 0. and 6 attached thereto is operatedupon at each downward movement of such head and parts. The conveyer Creceives and conveys the pallets from where received to and away fromthe molds and is preferably arranged at substantially right angles tothe movement of the chain or belt to which the molds A A &c., aresecured, as seen in Fig. 6. This conveyer preferably consists of twolink chains'C G which are connected together by rods having a roller orother suitable bearing at each end to en.- gage with a suitable supportX by which the pallets E, E, &c., carried by the conveyer are held inoperative relation to the brick machine. These link chains C C arepreferably composed of links of uniform dimensions adapted to be mountedon the octagonal pulleys 0, 0, as seen in Fig. 2 which are suitablymounted on the frame Y of the conveyer.

The pallet conveyer link chains C C are caused to move a distance equalto something more than the length of the pallet into position relativelyto the the pallets are to recei e the bricks or other structures, asejected therefrom, by means of the pawl D which engages with the chainsas seen at the right of Fig. 2, and is connected to the main drivingpart Z by connecting links 03, (Z, (Z, (Z, cl, shaft (Z and the armsthereon arranged as shown. This conveyer belt or chain is adapted toreceive the pallets, as they may be fed to it, and be proper distancesinto position the molds to receive the bricks relatively to the same areejected or other structures as therefrom.

In this preferred construction means are provided by which the pallets,carried by the conveyer, are moved individually toward and away from themolds when they are brought into position to receive the bricks or otherstructures, as the same are ejected therefrom. This movement causes thepallets to close the open side of each mold as it is brought intoposition for the ejector to operate and remove the compressed materialtherefrom. This movement is caused to take place by means, which consistof two parts H, H, movable upwardly and. downwardly, as the pallets areto be moved, in a suitable frame attached to the conveyer mechanism. Oneend of each of these parts is adapted to engage with a pallet, as it isto be moved to close the open side of the mold. The other end of each ofthese parts H, H, is

molds, from which r connected to a link H H between the ends thereof, asseen in Fig. 1. These links H H ,are at one end pivotally mounted to theframe of the machine, the other ends being similarly attached to one endof each of the links H H These links have their other ends pivotallyattached to the lower end of the arms of the rock shaft H This rockshaftH has an arm H? to which is attached one end of a link H the other endof which is connected with the main driving part Z. All of these severalparts are so proportioned and constructed that when the pallet isbrought into position to receive the brick from the mold they cooperatewith molds, ejector mechanism andwith one another to receive the brickfrom the molds as follows: The parts H, H, will engage with the palletand move it toward the mold and close the same, ready to receive thebrick or other structures as the same are ejected from the mold. Aboutthe time the pallet has closed the mold, the part b of the ejectormechanism starts toward the mold and comes into contact with thematerial therein to eject it therefrom. From the time this part Z) comesinto contact with the material to eject it from the mold the part b andthe parts H, H, move preferably at the same speed and to the same extentor in substantial unison one with the other during the operation ofejecting the material and depositing the-pallet on the conveyer, withthe material thereon, in position to be carried on toward the pointwhere the same is to be removed from the conveyer and placed on the carto be taken to the drying room or other desired point in the works.

By this movement in unison of the parts named in thepreferredconstruction shown the material is held in place and ejected from themolds and deposited on the pallet with little or no danger of beingdisturbed or distorted in form, thereby increasing the proportion ofperfect brick or other structures formed and delivered by the machine.

If desired a scoring device as I may be attached to the hollow bed plateof the brick machine, as seen in Figs. 1 and 4, by which one side of thebrick or other structures may be scored or grooved to receive the mortarwhen laid up .in a wall. This scoring device as I consists of a bar Ihaving projections seen in Fig. 4 of the drawings. This bar ispreferably arranged at the end of the bed plate X and at substantialright angles to the path of movement of the molds through preferablyyieldingly containing the compressed material are preferably secured inplace, as shown. Pins i i, &c., are secured to the sides of the links towhich the molds are attached, as seen in Fig. 1, which cooperate withthe cam surfaces formed on the upper edges of the pivoted levers I 1 tomove the scoring bar I which is attached to the free ends of levers I 1to move such bar out of scoring position and out of contact with themolds as they pass by the scoring device. The bed or hollow support X ispreferably supplied with rollers or other suitable means :0, 50, &c.,for holding the molds A A into desired contact with the hollow bed plateX. This hollow bed X is preferably provided with suitable pipes andvalves, for connecting such bed with a supply of steam, as shown at P, Pnear the ends thereof, for heating the same and more or less heating themolds and material therein, thus preventing adhesion of such material asit passes over such bed.

Instead of moving the pallet alone toward and away from the mold toclose and open the same to receive the brick or other structurestherefrom, as shown in Fig. 2., the conveyer chains, with the palletthereon, may be moved toward and away from the molds to close and openthe same, as shown in Fig. 7.

If desired the partial heating of the material may be omitted and theconveyer used in operationwith the mold filling chamber, the compressingand ejecting mechanism, as the same is sometimes shown in the prior art,and as illustrated in Fig. 7 of the drawings. The general arrangement offilling chamber, compressing and ejector mechanism is well known in theart and does not need any detailed description herein to be fullyunderstood. Also, if desired the repressing the brick a second time maybe dispensed with and without in any way changing the cooperation of thepallet conveyer with the ejector mechanism of the machine, as will bemanifest to those skilled in this art.

If desired, the means shown in Figs. 1, 2 and 3 and described herein formoving pallet toward and away from the mold to close and open the samemay, when slightly modified, be used for moving pallet and chain links CC toward and away from the mold, or any other desired form of mechanismmay be used for this purpose.

The construction thus shown may have the moving parts H, H, so changedthat instead of engaging directly with the pallet alone that they bemade to engage directly with the chain links themselves, so as to movesuch links and pallet bodily to close and open the molds. These parts H,H, seen in Fig. 2 are H H in Fig. 7 It is believed unnecessary tofurther describe this mechanism in detail that is indicated in Fig. 7 inorder that it be fully understood.

Or when the material is of a nature to be compressed and remain in thecompressed form and remain intact during the operation of being ejectedfrom the molds, the closing and opening of the molds may be dispensedwith and the pallet conveyer be advantageously used without the palletbeing moved toward and away from the molds, as shown in Fig. 8, whereinthe chain links C C may be arranged a sutlicient distance away from themolds to permit the pallet and brick upon the same to freely pass bythem as the pallet is conveyed away therefrom to the point where thepallet with the brick upon it, is to be removed from the machine. hen soarranged the pallet may remain stationary, or nearly so, when receivingthe brick or other structures upon being ejected from the molds. In sucha case the parts If, H, and H, H and the mechanism by which they areoperated is dispensed with, the cooperation of the conveyer with themold and ejector device being substantially the feeding of the palletsinto the machine to receive the brick and convey them to the point wherethe same are to be removed.

The operation of brick machines of the general class herein shown iswell known to those skilled in this art. Consequently, it is onlynecessary to describe the operation of the conveyer in connection withthe general class of machines shown. The conveyer and operatingmechanism, as shown, is so combined with a machine having means forejecting brick or analogous articles from the molds that the conveyeroperates intermittently in unison with the intermittent movement of themolds. Consequently, the endless conveyer chains or belt may, as seen inFigs. 1, 2 and 8, remain substantially stationary while the palletsreceive the compressed material as the same is ejected from the moldsafter being formed or shaped therein. As shown in Fig. 7 the conveyerchains or belt, as before explained, are moved toward and away from themolds and cause the pallets to correspondingly move to close and openthe molds while the material is being ejected therefrom. At eachrevolution of the wheel or shaft Z of the brick machine the bar or linkd and rock shaft 1 with the links or connections (Z, d, &c., the pawl Dis caused to take on a forward and backward movement and as the free endof this pawl engages with the chain links C C as it starts forward, suchchains or belt is moved forward a little more than the length of apallet as E see Fig. 2, into position to receive the brick or similararticles as they are ejected from the molds. During the backwardmovement of the pawl D it is brought into position to again engage withthe chains C C or belt ready to move the same a distance forward tobring another pallet into position to receive the brick from the same,so far as concerns another mold. 'lVhen the pallet is thus brought intoposition the pallet, as seen in Figs. 1, 2 and 7, is moved into positionfor it to close the mold by the operation oi the parts H, H, and H Hthrough means of the links or parts as they are moved by the oscillationof the levers H H through their being connected with the cam which movesas the main wheel or shaft Z moves, when it is in motion, by means ofthe connecting parts H H H H and H", co operating with such cam. As seenin Figs. 1. and 2, the parts H, H, engage directly with the pallet toclose and open the mold, while in Fig. 7 the parts H H engage directlywith the chains 0 C and move the pallet upon them to close and open themold.

I have shown and described that diiiierent combinations of parts havingspecific characteristics and different specific constructions or formsof parts may be used in the place or places of some that are hereinshown without in any way changing the character or cooperative relationsof the parts of such combinations, as must be manifest to a mechanic,and therefore, I do not wish to be limited to the specific forms andconstructions of parts herein shown, but wish to include each and allthat are within the spirit of my invention.

l V hat I claim as new is 1. In a machine having molds open on oppositesides, a stationary bed over which Copies of this the molds move,pressing and ejecting means for forming brick and analogous articles,the combination, substantially as described, of a pallet conveyorarranged adjacent to the stationary bed adapted to receive and conveypallets into register with the ejector means and means adapted to engagedirectly with the pallet received by the conveyer and move itindependently of the conveyer toward and away from the mold to close thesame to receive the formed brick and return the pallet to the conveyer.

2. In a machine having movable molds open at top and bottom, pressingand ejecting mechanisms movable toward and away from the top portion ofthe molds for forming brick and analogous articles, the combination,substantially as described, of a bed or support over which the moldsmove into reg-' ister with the ejector mechanism, movable scoring meansconstructed and arranged to enter the mold, and means adapted to movethe scoring means into that side of the mold opposite to that at whichthe ejector enters to score or roughen one side of the contents thereof.7

In testimony whereof, I have signed my name to this specification in thepresence of two subscribing witnesses.
